rpm: correct AutoRequires filtering on recent Fedora

Recent Fedora releases (F17 and newer) do not need the
__requires_exclude macro for filtering automatically generated Requires
for <xlator>.so files anymore. It is already sufficient to filter each
<xlator>.so from the Provides.

This prevents the following (harmless) warning from being printed during
build:

    Ignoring invalid regex -P ^(?!lib).*.so.*$
